Understanding EWG Ratings

EWG Ratings

The Environmental Working Group (EWG) empowers people to live healthier lives in a healthier environment.  This is something that we feel very strongly about and it’s the foundation on which Revescent is built.

The EWG’s Skin Deep project is the world’s largest personal care product safety guide. They have created a core, integrated database of chemical hazards pulled from the data of nearly 60 databases from government agencies, industry panels, and academic institutions. This database allows them to assess potential hazards and data gaps for cosmetic ingredients. These ingredients are evaluated on primary and secondary references of known and probable carcinogens (a carcinogen is any substance, radionuclide, or radiation that is an agent directly involved in causing cancer), reproductive and developmental toxicants, neurotoxicity, immunotoxicity, persistent bioaccumulative toxics (bioaccumulation occurs when an organism absorbs a toxic substance at a rate greater than that at which the substance is lost), and their restrictions and warnings on safe use of ingredients in cosmetics.

The studies and data contained in Skin Deep are categorized into 17 general hazard categories: cancer, reproductive/developmental toxicity, neurotoxicity, endocrine disruption potential, allergies/immunotoxicity, restrictions/warnings, organ system toxicity, persistence/bioaccumulation, multiple/additive exposure, mutations, cellular/biochemical changes, ecotoxicity, occupational hazards, irritation, absorption, impurities, and miscellaneous.

After careful evaluation, EWG then applies a “hazard” or concern rating to each product based on the findings of each individual ingredient. These ratings consider potential health hazards but does not account for exposure or individual susceptibility. Hazard ratings are low (0-2), moderate (3-6), or high (7-10) concern.

Revescent relies heavily on these ratings in evaluating the quality and safety of the personal care and cosmetics products it sells, and generally only products that have achieved low 0, 1, or 2 ratings, or their equivalent, are considered acceptable to us.
